Recently it has become very difficult to start. You have to bury the accerator pedal and once it catches it runs very rough until it warms up. Once it warms up its fine.I have replaced the fuel filter and checked to make sure the fuel pump is working(it is).

The only other thing I have noticed is once it catches and starts to run from a cold engine you smell fuel from the exhaust until it warms up.

Best place to buy is online as most parts houses want 100+ for the CTS (coolant temp sensor). Rockauto.com is my favorite as they have good prices on SMP (standard motor products) which IMO is a good line. (SMP is also BWD, fyi)

What you could do as well is unplug the CTS (green, two wire sensor just under the thermostat goose neck) and see if it changes how it starts/runs.

Haven't had a chance to test the sensor yet. It was raining
For days and I'm just getting over the flu.
Does any one know if the TCS on other year subarus
Will fit my 91? I can't imagine a different Sensor for every
Model and year. But I'm headed to the boneyard Monday to look
For a Subby.

I was able to clean the scale off of my sensor, in this case it made the car run and idle . if you have a volt ohm meter you can check the sensor, I used a pan of water on the stove , as it heated the resistance changed . not sure of the specs for the sensor .
